List of vulnerable invertebrates

As of July 2016, the International Union for Conservation of Nature (IUCN) lists 2178 vulnerable invertebrate species.[1] 12% of all evaluated invertebrate species are listed as vulnerable. The IUCN also lists 47 invertebrate subspecies as vulnerable.

Invertebrate species (IUCN, 2020.1)
  • 17,646 extant species have been evaluated
  • 12,368 of those are fully assessed[a]
  • 8024 are not threatened at present[b]
  • 4328 to 9606 are threatened[c]
  • 410 to 616 are extinct or extinct in the wild:
    • 395 extinct (EX) species[d]

Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild.

No subpopulations of invertebrates have been evaluated by the IUCN.

For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered invertebrates, List of critically endangered invertebrates. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN.

Additionally 5278 invertebrate species (29% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.[2] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."[3]
